People buy more junk food when using plastic

''The pain of paying in cash can curb impulsive urges to purchase unhealthy food products,'' Thomas writes with his co-authors in the June issue of the Journal of Consumer Research. "Credit card payments, in contrast, are relatively painless and weaken impulse control.''

The researchers analyzed the spending habits of 1,For all DVS Bedding in PDF format.The Leading promotional usb Distributor to Independent Pet Retailers.000 shoppers at a large chain store over six months in 2003 and then conducted two controlled experiments at Cornell and SUNY Binghamton, as well as an online experiment.

Previous studies had found that consumers are more reluctant to part with bills and coins than to use credit -- what the research has labeled "pain of payment." Thomas' team, however, established that the "pain" of paying in cash really only affects impulsive purchases of "vice" foods and not deliberate "virtuous" purchases. There was no difference, however, when consumers used credit and debit cards to buy food -- an unexpected finding.

"This is surprising," Thomas said, "because, unlike credit cards, debit cards are equivalent to cash; the money gets deducted from the consumer's bank account almost immediately. This result suggests that ¡­ even the mere abstractness of plastic payments can reduce the pain of payment and thus influence consumers' purchase decisions.What to consider before you buy Wholesale pet supplies."

The key to understanding the findings, Thomas said,GreenRay's hydraulic hose design uses a different energy storage approach, is that the so-called "vice" foods,Welcome to the official Facebook Page about RUBBER MATS. such as Oreos and Coca-Cola, for example, are perceived as unhealthy and impulsive to buy. Shoppers therefore relate to vice foods on a purely "visceral" level, Thomas said, whereas they consider "virtue" foods (Quaker Oatmeal and Aquafina Pure Water, for instance) at a rational level as "utilitarian" products.

"So vice spending is more susceptible to pain of payment," Thomas said, and thus, to payment in cash, while form of payment doesn't affect virtue spending.

The findings not only showcase an interesting quirk of consumer psychology but also may help curb the epidemic of obesity in America today, said Thomas, who hopes that for some consumers, at least, the use of cash over cards might help them cut down on impulsive and unhealthy food purchases.

Thomas noted that various technological advances in the near future may also help consumers at the cash register.

"I believe and hope that we will soon start seeing technological advances in credit and debit cards that help consumers better manage their spending decisions," Thomas said. "For example, it might be useful to have an LCD chip in a card that shows the total monthly spending thus far, or the cumulative credit."

Co-authors of the study are Kalpesh Kaushik Desai, associate professor at SUNY Binghamton, and doctoral student Satheeshkumar Seenivasan of SUNY Buffalo.

Alta Devices hits new record solar panel efficiency

Stealthy solar panel manufacturing startup Alta Devices announced today that it has produced solar panels that have broken previous efficiency rating records for solar panels.

Alta Devices said it was able to produce Gallium Arsenide solar panels that capture 28.2 percent of the light shining on the panel and convert it to electricity, up from a previous efficiency rating of 27.6 percent that the company produced last year.The name "magic cube" is not unique. The last record for solar panel efficiency rating was 26.4 percent, according to results verified by the National Renewable Energy Laboratory.

Wafer-style solar panels have a theoretical efficiency rating of 33.5 percent, according to the company. Alta Devices appears to be developing solar panels that will eventually reach that efficiency rating.Our Polymax RUBBER SHEET range includes all commercial and specialist The company is one of several solar panel manufacturers that focus on wafer-style solar panels that operate best in clear days when the sun is shining directly on the panel.

Thin-film solar panels like those that First Solar manufacture do not have efficiency ratings as high as those types of solar panels.Welcome to the official Facebook Page about Ripcurl. But they are able to perform better in diffuse light situations and in high-temperature environments,Handmade oil paintings for sale at museum quality, said First Solar's Pam Hegarty. Those panels take up more space than crystalline solar panels and cost more to install, but can generate more electricity in non-optimal environments, she said.

"All things being equal, those systems have a higher conversion efficiency," she said. "But when the sun is not at a 90 degree angle,you will need to get an offshore merchant account. thin-film solar cells absorb more of that light and has a broader energy curve than crystalline silicon panels."

Alta Devices recently raised $72 million in its most recent round of funding despite still being in stealth mode. A job posting at the time indicated the company wanted to develop photovoltaic cells that are around 30 percent efficient and can generate 1 watt of electricity at a cost of 50 cents.

The Santa Clara, Calif.-based company plans to move a few minutes north to Sunnyvale, Calif., according to Green Tech Media. It has 55 employees and has filed for 35 patents, according to the job posting. The company also received a $3 million grant from the Department of Energy to develop low-cost and highly efficient photovoltaic cells.

The new Siemens "Aquaris" hearing instrument is watertight and robust

Chicago, USA / Erlangen, Germany, Whether it is being used during leisure activities

or in a work environment, the new Siemens "Aquaris" hearing aid copes with many

challenges. It is not only watertight and dustproof, but also robust and impact-

resistant. These qualities are achieved by features such as a special casing with a

sealed battery compartment, a watertight microphone membrane and a protective cover.

A slip-on sports clip holds the hearing instrument securely behind the ear, even

when the wearer is moving around or being jolted. The "BestSound Technology"

developed by Siemens guarantees enhanced hearing comfort, even in difficult noise

environments.

Manufacturing a hearing aid that not only repels water, but is truly waterproof,

represented a particular challenge for the engineers. In traditional hearing aids,

there are a number of points through which water can penetrate and damage the

sensitive technology inside. These include not only the tiny screws that normally

hold the casing together, but also the battery compartment and the microphone and

earpiece sockets.

To cope with this, Siemens developed a one-piece casting for Aquaris. A

scratchproof, rubber-like surface holds the device securely behind the ear and

prevents it from slipping. The battery compartment is equipped with a waterproof but

air-permeable membrane. As a result, environmentally-friendly zinc air batteries can

be used, which always require "air to breathe". The cover clip is attached to the

top of the casing via ultrasound. It also protects the waterproof but acoustically

transparent microphone membrane, which was specially developed for Aquaris. A nano

coating and a seal protect the earpiece.

The result speaks for itself: Siemens engineers tested Aquaris under severe climatic

conditions, including in tropical Australia. Independent institutes also tested the

device for compliance with the relevant standards. For example, it was submerged for

30 minutes at a depth of one metre without water penetration. As a result, Aquaris

can officially be described as "waterproof".

Aquaris hearing aids are ideal for anyone with impaired hearing who undertakes

sweat-inducing activities either as part of their job or in their leisure

activities, or who spends time in a damp or dusty environment. They are equally

reliable even in floury bakehouses and building sites. They can be worn when

sailing, surfing or even swimming. A swimming program developed by Siemens itself

deals with the special acoustic conditions encountered during swimming while the

cover clip on top of the device absorbs even the strong wind noise.

The casing protects the sensitive inside workings not only from damp and dirt, but

also from impacts and jolts, such as can occur when playing sport. When the wearer

is involved in sports such as mountain biking, jogging and beach volleyball, where

there is extensive movement, a slip-on sports clip holds the device securely behind

the ear.

Just like the entire latest generation of Siemens hearing aids, Aquaris is equipped

with the BestSound Technology developed by Siemens, which ensures true sound comfort

and excellent speech understanding. The wearer is able to make adjustments using

Siemens "Tek" and "miniTek" remote operation, and can link the hearing aids

wirelessly with modern communication and entertainment electronic devices. Siemens

produces a waterproof "Aquapac" to protect this remote operation facility.

The planned market launch date for "Aquaris" is June, 2011.

The products mentioned here are not yet available for purchase in some countries.

Due to regulatory reasons, future availability in any country cannot be guaranteed.
